What the site does
The site brings together product reviews, buying guides, evidence reviews, side-by-side comparisons and a running-cost calculator. It doesn’t sell anything, take orders or offer medical services. Buttons that say “Check price” take you to the brand’s or a retailer’s store.
It covers nine categories, each with its own buying guide:
- Saunas, infrared and traditional
- Red-light therapy masks and panels
- Cold plunges and contrast therapy
- Sleep and bedding: bed cooling systems, sheets and sleep masks
- Blood, biological-age and glucose testing
- Sleep and recovery wearables
- Third-party-tested supplements
- Water filters
- Air purifiers
How to read a review
Each review names one model or variant. It keeps maker specifications apart from certification scope, regulator records, published studies and our analysis. Anything we could not confirm is listed as unknown. Our evidence rating method explains how we assess a health claim.
Prices are what the maker’s store showed on the date given, for the variant named. Where the maker showed no price, we use a named retailer’s listing or the launch price if we found one, and the review’s price note says which. Prices change, and tax, shipping and installation may be extra. The site doesn’t promise how a product will perform in your home or what it will do for your health.

How the site is funded
We plan to fund the site through affiliate links, not ads or sponsored posts. Each review says under its price button whether that link earns us a commission, and a commission never decides a pick. Our funding page explains the disclosure and our editorial policy explains how research, corrections and ratings are handled.
